Grady Hillhouse is a professional civil engineer and hobbyist everything else in San Antonio, Texas. Randall Munroe said, "You can look at practically any part of anything manmade around you and think, Some engineer was frustrated while designing this. It's a little human connection." My goal for Practical Engineering is to increase exposure and interest in the field of engineering. I'm trying to highlight that connection between the world around us and the energy, passion, and thought that goes into making it a nicer place to live.

Hydraulic transients (also known as water hammer) can seem innocuous in a residential setting, but these spikes in pressure can cause major damage to large pipelines and industrial pipe networks. In this video, we briefly discuss how water hammer occurs and how engineers mitigate the effect.

What is Concrete?

What's the difference between concrete and cement? Support for this video comes from Brilliant: Concrete is the most important construction material on earth and foundation of our modern society. At first glance it seems rudimentary, but there is a tremendous amount of complexity involved in every part of designing and placing concrete. This video is meant to be a bare-bones introduction to the topic, with a cool demonstration of concrete strength using a hydraulic press. -Patreon: -Website: Marxist Arrow by Twin Musicom is licensed under a Creative Commons Attribution License Source: Tonic and Energy by Elexive is licensed under a Creative Commons...

The Causes and Effects of Water Hammer

Water hammer has the potential to rupture valves, pipes, and fittings. Condensate can collect on the bottom of steam lines, out of the flow path, so it requires some external means, like gravity for instance, to move it through the system. While damage is most often caused by repeated occurrences of water hammer, sometimes damage can be immediate and catastrophic, and sometimes harmful to employee safety. Armstrong International has released an updated interactive 30 minutes course on Water Hammer. The course objectives are: --Understand basic mechanics of water hammer --Identify conditions under which water hammer may occur --Apply preventative solutions...

Sand Castle Holds Up A Car! - Mechanically Stabilized Earth

Dirt is probably the cheapest and simplest construction material out there, but it's not very strong compared to other choices. Luckily geotechnical engineers have developed a way to strengthen earthen materials with almost no additional effort - Mechanically Stabilized Earth (aka MSE or Reinforced Soil). If you look closely, you'll see MSE walls are everywhere. Thanks for watching, and let me know what you think!

What is Valve Cavitation? (Animation)

Learn about valve cavitation and how damage can be reduced or prevented. Key Points: – Cavitation occurs when the fluid vaporizes then returns to a liquid state as the pressure increases downline. – Cavitation can cause unacceptable noise and vibration that reduce efficiency or lead to loss of process control. – Cavitation damage can be reduced by altering or accommodating valve construction materials or staging pressure drops.

Does Rebar Rust?

Check out the first two videos on concrete if you haven't seen them already: - What is Concrete? ( - Why Concrete Needs Reinforcement ( While steel reinforcement solves one of concrete’s greatest limitations, it creates an entirely new problem: Corrosion of embedded steel rebar is the most common form of concrete deterioration. There are lots of ways to combat this problem, a few of which we discuss/demonstrate in this video, including fiber reinforced concrete, adequate protective cover, and fiber reinforced polymer bars. -Patreon: -Website: Tonic and Energy by Elexive is licensed under a Creative Commons Attribution License Source:

How Soil Destroys Buildings

Okay this is the last video on the hazards of soil mechanics for a while :) Support for this video comes from Brilliant: Expansive soils cause more property damage per year than earthquakes, floods, hurricanes, and tornadoes combined. Expansive soils are a slow-moving geologic phenomenon, which makes them not very news-worthy. However, they still cause a tremendous amount of damage to buildings and the public infrastructure we rely on every day.

Why Concrete Needs Reinforcement

More destructive testing to answer your questions about concrete. The first 1000 people to click will get their first 2 months of Skillshare for free: Concrete's greatest weakness is its tensile strength, which can be less than 10% of its compressive strength. So, we often reinforce it to create a composite material strong against all types of stress. This video briefly touches on conventional rebar and prestressed/post-tensioned reinforcement. -Patreon: -Website: This video was sponsored by Skillshare.
